IMPRGVEMENT IN ELECTRO-MAGNETIC REGISTERING APPARATUS FOR TURNSTILES.

Specification forming part of Letters Patent No. 9236 1, dated June 26,1877; application filed March 30, 1877.

, To all whom it may concern with suitable mechanical devices, and asuit-- able registering mechanism, for the purpose of registering thenumber of persons entering or leaving a bridge, ferry, hall, room, orother inclosure.

In the drawing, Figure 1 represents a plan or top view of myimprovement, partly in sec tion. Fig. 2is a longitudinal verticalsection. Fig. 3 is a side view of the dial-plate and its frame.

My invention is described as follows: At the entrance of the ferry,bridge, or inclosnre is placed a turnstile consisting of a revolvingvertical shaft, A, provided with four arms, b, so situated with regardto each other that a person entering from either side of the entranceshall push against one of said arms I) and cause the shaft A toperformone-quarter of a revolution. The upper part of the shaft A passesthrough a suitable frame-work made so as to support a circular disk, B,of wood or metal, which turns loosely on shaft. A. Directly above thedisk B, and in contact with it, is a smaller circular disk, 0, which isfixed to and turns with shaft A. This disk 0 has a portion of itsperiphery cut into cogged teeth, which engage with corresponding teethof a pinion-wheehc, which is vertically secured to the lower and largerdisk B. The object of the cogged teeth on disk 0 and the pinionwheel 0is to prevent the registering mechanism, which will be hereinafterdescribed, from registering until the shaft A has performed nearlyone-quarter of a revolution, thus preventing the registering mechanismfrom acting on any slight movement of the shaft A, and doing away withany tendency to accidental registration.

The pinion-wheel c is provided also with a pin, cl, fixed horizontallyto it, which pin (1 strikes against either of the two pins, (1 or (Zsecured vertically to the disk 0.

The object of these pins 01 d d is to save the cogs on the disk 0 and onpinion c from excessive strain or wear. A

On the periphery of the large disk B, fixed horizontally, is a pin, 6,which, as the disk 8 is made to revolve with shaft A, at every quarterof a revolution of shaft A, strikes against a button or circuit-closer,D, D D and D which are placed at proper distances apart and around thedisk B. These circuit-closers are connected by a wire, f, with eachother and with one of the poles, g, of a galvanic battery.

The disk B is connected with the other pole, h, of the battery, by meansof the button or circuit-closer f, to which is connected the wire 70,which passes through the electro-magnets G and G and thence to the poleh.

Working in connection with the electromagnets G and G is the armature H,to which is secured a vertical lever, L. Attached to this lever L is oneend of spring m, which has its other end secured to a standard, a. (SeeFig. 2.) At the upper end ofthe vertical lever L are two pawls, O and P,one of which pawls, O, is secured to one side of the vertical lever L byscrews or other suitable means, and the other pawl, P, is pivoted tosaid vertical lever L through a slot cut in. its top, and is sup portedby a spring, 19, placed under it.

These pawls engage with the teeth of the ratchet-wheel R. The object ofthese pawls O and P is to communicate a rotary motion to theratchet-wheel R, and at the same time to prevent the ratchet-wheel Rfrom moving more than the space of one of its teeth at one motion. Theratchet-wheel R is attached to a shaft, R, to which is fixed aregistering indexhand, S, which moves around the face of a dial-plate,S, which dial-plate is furnished with a suitable index for registeringthe number of persons entering or leaving the ferry, bridge, or otherinclosure. In connection with the ratchet-wheel R is a pawl, T, thepurpose of which is to prevent the ratchet-wheel R from turning backafter having moved the space of one of its teeth.

The shaft B may be provided with a pinion, to which may be attachedsuitable mechanism for registering up to'any number desired.

The operation of my invention is as follows: When a person enters theentrance-way where the turnstile is placed and attempts to pass theturnstile he imparts motion to the shaft A, and as he passes throughcauses it to perform onefourth of a revolution. The movement of theshaft A turns with it the circular disk 0, fixed to the shaft A. Themotion of the disk 0 is communicated by means of the cogged teeth outin, and one of the pins (1 or d fixed to said disk 0, to the pin 01 onpinion-wheel a, secured to the disk B. The circular disk B is thuscaused to revolve. This movement of the disk B causes the pin 6,projecting horizontally from the circular disk B, to strike against oneof the buttons or circuit-closers D, D D or D arranged at properintervals around the disk B.

A current of electricity then immediately passes from the pole g of thegalvanic battery through the wire f, and through the disk B and buttonF, and thence through the wire K to the electro-magnets G and G. Thepassage of the current of electricity immediately causes these magnets Gand G to attract the armature H. The attraction of the armature H to theelectro-magnets G and G causes the lever L to move and the pawl P,connected with it, to engage with one of the teeth of the ratchet-wheelR, and to move the said ratchetwheel B the space of one of its teeth,and imparts a rotary motion to said ratchet-wheel B.

The movement of the lever L also causes the pawl O to engage with theteeth of the ratch etwheel R, and prevents it from moving more than thespace of one of its teeth at one motion of the armature H and lever L.At the same time the movement of the pawl T prevents the ratchet-wheel Rfrom turning back after having moved the space of one of its teeth.

The rotary motion of the ratchet-wheel B. on its shaft or arbor R causesthe index-hand S to move over the face of the dial-plate S and register.

By the above means a perfect and accurate automatic register is formed.

Having thus described my invention, what I claim is- I 1. The shaft Aand circular disk 0, having a portion of its periphery cut withcog-teeth and provided with pins (1 and 01 in combination with thecircular disk B, provided with the pin 01 and pinion-wheel c,substantially as described.

2. A turnstile consisting of the shaft A and disks B and G, incombination with the magnets G and G, and connected therewith by meansof a current of electricity passing through suitable circuit-closers,and actuating the armature H, pawls O, P, and T, lever L, ratchet-wheelB, and any suitable registering mechanism.

3. A turnstile consisting of shaft A and disks B and U, in combinationwith the magnets G and G, and connected therewith by means of a currentof electricity passing through suitable circuit-closers, and actuatingthe armature H, pawls O, P, and T, lever L, ratchet-wheel R, index-handS, and dialplate S, substantially as described.

4. A turnstile consisting of the shaft A and disks B and G, incombination with the electro-magnets G and G, and connected therewith bymeans of a current of electricity passing through circuit-closers D, D Dand D and pin e on disk B, and button F, and actuating the armature H,lever L, pawls O, P, and 'I, ratchet-wheel R, and any suitableregistering mechanism.

5. A tnrnstile'consisting of shaft A and disks B and C, in combinationwith the electromagnets G and G, and connected therewith by means of acurrent of electricity passing through circuit-closers D, D D, and D andpin 5 on disk B, and button F, and actuating the armature H, lever L,pawls O, P,

and T, ratchet-wheel R, and any suitable registering mechanism.

In testimony that I claim the foregoing l have hereunto set my hand this29th day of March, 1877.
